1. Overview
------------------------------------------------------------

This archive contains replication materials for the study
"Conditions of Confinement: Do Harsher Prison Conditions Reduce
Political Participation?"

The study evaluates whether exposure to harsher prison
conditions affects subsequent political participation,
including voter registration and turnout. Analyses rely on
individual-level administrative incarceration records merged
with facility-level measures of prison conditions and election
participation data.

All results reported in the associated manuscript can be
reproduced using the files contained in this archive, subject
to the limitations described below.

------------------------------------------------------------
2. Data Description
------------------------------------------------------------

The replication data consist of cleaned, analysis-ready
datasets derived from restricted administrative records.
Original raw data are not publicly distributable due to data
use agreements and human-subject protections.

Publicly released files contain no direct personal identifiers.

------------------------------------------------------------
3. Anonymization and Confidentiality
------------------------------------------------------------

To protect the privacy of incarcerated individuals, all
personally identifying information has been removed or
transformed prior to public release.

Each individual is identified using an anonymized identifier
(control_number). This identifier was generated by applying a
cryptographic hash function (SHA-256) with a private salt to
the original administrative control number. The salt is not
included in this archive and is retained privately by the 
author.

------------------------------------------------------------
4. File Structure
------------------------------------------------------------

This archive includes:

- Cleaned analytic datasets used in the main analyses
- R scripts used to construct variables and reproduce all
  tables and figures

------------------------------------------------------------
5. Software Requirements
------------------------------------------------------------

Analyses were conducted in R.

Required R packages are listed and loaded within the
replication scripts.

------------------------------------------------------------
6. Replication Instructions
------------------------------------------------------------

1. Unzip the archive.
2. Set the working
   directory to the project folder.
3. Run the replication scripts in the order they are listed
   or simply execute all files at once with 0_master.R

------------------------------------------------------------
7. Limitations
------------------------------------------------------------

Because some source data are restricted, replication relies on
derived datasets rather than raw administrative records.
Researchers seeking access to original data must obtain
approval directly from the Pennsylvania Department of 
Corrections.
